Under EN 60898-1 it's rated 10 kA at 230 V AC; under IEC 60947-2 it jumps to 35 kA at 230 V AC. For DC circuits, it's rated 15 kA at 60 V (72 V max). It also carries a UL 1077 / CSA C22.2 No.235 listing at 5 kA, so it's accepted in North American panels that recognize supplementary protectors. If your BOM calls for a breaker that meets both IEC and UL, this one covers both without a second line item. ## Mounting and environmental fit Snaps onto any DIN rail (the 'quick assembly system' fastening), and the combined top and bottom terminals let you daisy-chain busbars or wire in and out without extra jumpers. The sealable option (padlockable toggle) is handy for lockout/tagout on a machine circuit. Rated IP20 with conductors connected — that's typical for inside a closed panel, not for washdown areas.","metaTitle":"Siemens 5SY4502-7 SENTRON MCB, C-Curve 2-Pole 10kA, 36mm Wid","metaDescription":"Siemens 5SY4502-7 SENTRON miniature circuit breaker, C-curve, 2-pole (1P+N), 10 kA per EN 60898-1, 35 kA per IEC 60947-2.
